Source for 5/8"-11 plugs for AFR-185 heat pump holes?
Okay, I've looked at boltdepot.com, graingers, and fastenal, and even Ford Racing and AFR themselves, and I cannot find a source for brass, stainless steel, or chrome (or any metal, really) threaded plugs for the 5/8"-11 threaded heat pump holes on the front and back of my AFR-185 heads. :JEKYLHYDE
Am I missing something here? I suppose I could use bolts, but the elegant solution is chrome or stainless steel countersunk hex (Allen) plugs. :cool: As I'm not in a total hurry as I assemble my 331, I've got time. However, there is a point at which one must admit this effort is ridiculous---hmm, I've already passed that point, now, haven't I?. Anyhow, sage advice welcome. Where (Oh, where!) can I obtain these plugs? :confused::confused::confused: DD |
Doug check A&A Bolt and Fastener in Baltimore. They have an incredible variety. Their phone is 410-687-8831. Best of luck. Tom

I know edelbrock supplies them when you buy there heads, I would try a automotive machine shop. I would also try mike forte from forte's parts connection I believe he stocks them.

if you have a bolt you could cut to length then slot for a screwdriver

Call Keith Craft. They installed the ones in the 185,s I bought from them. The insert also allows the use of a slightly smaller bolt as they are threaded on the inside as well. Awesome company and service bar none.

Aren't these an OEM Ford part used on the 5.0 heads. I had to get them for use on my World products heads. The heads are then essentially plugged on then both ends the threaded inserts are internally threaded and allow accesory bolts to be used. Otherwise the heat tubes that are part of the OEM emission system use a hollow banjo bolt that screws into them on the firewall end with one of the mentioned plugs at the front of each head, allowing for accessories to be attached at the same time.

you call them plugs but a 5/8-11 is a standard machine screw thread, so a set screw will be the only thing out there...the above is a link to some SS ones , pg 3072 about halfway down, 18-8 SS,,,,choice of lengths |
I had an "aha!" moment when I removed one of the thread reducer inserts from one of the holes---the inserts are capped on the inside end, making them a seal in and of themselves. So, to seal these holes you could just use four inserts, one on each end of both heads.
Looking for something else today down at the hardware store I found a separate section of the set screws and found the 5/8"-11's there. So, in case someone else stumbles across this thread looking for answers... DD |
The ford part works great - Or cup set screws like ; McMaster-Carr
